Reference value of first group of data (R) (IEEE 32-bit floating-point value)

17-18

Decimal scale factor (D)

19

Number of bits to pack each value of the first group of data with

20

Type of data in first group ("0"=floating point, "1"=integer)

21-N

The first group of data packed using the simple packing method

Notes:

1. Un-encoded value = (R + encoded value) / 10D.

2. The encoded values are treated differently based on the parameter and category number.
The typical method is to store text as a set of ASCII integers with a trailing 0 to
indicate the end of a row of a table.
